CARTON.

Application filed July 5,

My invention relates to cartons, and parf ticularly to cartons having dispensing spouts formed in cut and scored portions of the carton assemblies. Q It is the object of my invention to provide a carton having overlapping portions which normally form a closure for the package within the walls of which a dispensing spout is outlined in cut ands'cored lines, or in other readilyfrangible lines such as may be pro- :vided by perforations. It is further my object to provide a carton madefrom a cut and scored lank having a dispensing spout in the closing flaps thereof, which may beset 16 up on the ordinary sealing machine without the requirement of any additional mechanism. I propose to form walls of'a dispensing 3 out in what are ordinarily the top closing' aps of the carton, and to seal these flaps 20 on a mechanical bottom sealer first, and to then fill the carton bottom side up; and finally to close in and seal the bottom closing fla s after the carton is filled. While I find suc a procedure most practical from a manufacturing point of view I have so formed the cut and scored portions in the top closing fla s that these closing flaps may be closed in an sealed either before or after the filling of the carton.

I have as a further object the provision of adispensing spout formed in an underlying 7 portion of a carton in which an outer overlapping portion has a withdrawal tab so shaped that the proper folding of the side walls of the dispensing spout which is to be withdrawn through the aperture outlining the tab in the oute? overlapping portion along predetermined lines, will be enforced.

A further object is the disposition of nonadhesive areas on the overlapping portions so that a continuous application of glue over portions which are to be overla ped will not cause all the surfaces to which t e glue is applied to become adhesive;

' The above and other objects to which reference will be made during the ensuing disclosure, I accomplish by that certain arrangement and combination of parts of which I have shown a preferred embodiment.

In the drawings Figure 1 is a plan view of the cut and scored blank from which the carton illus trated is made.

Figure 2 is a top plan view of the carton w1th the end closure flaps folded in.

Figure 3 is a plan view of the carton with the end and one of the side flaps folded in.

Figure 4 is a plan view of the carton with the end and both side closing flaps folded in.

Figure is a side elevation of the carton with the d spensing spout'flap withdrawn.

Figure 6 is an end elevation of the carton shown as in Figure 5, with the dispensing spout withdraw Figure 7 is a sectional view on an enlarged scale along the lines 7-7 in Figure 6.

The carton is made from a blank having. I

side pieces 1 joined integrally with end pieces 2 by lines of articulation indicated at a-w..

I have further shown the extension 3 which provides means for attaching the portion 1 shown to the left in Figure 1 to the portion 2 shown to the right in Figure 1, Extending from the side walls I have shown the closure flaps 4, and extendin from the end walls, the closure flaps 5. i which my invention is applied has no particular importance, as the dispensing spout closure which I have provided may be formed in any walls of a carton in which there are overlapping portions.

I have selected the top closing flaps in which to outline in cut and scored lines, my novel dispensing spout 6, as I find that such an arrangement provides the most practical he type of carton to V position from the point of view of usefulness. 1

The end closure ap 5, as indicated, has a side walls of a dispensing spout. The side walls are formed by out lines Indicated at curved line bb which outlines the base and o0, and the back wall of the base of the the sealing of the closure flaps: An apphcation of paraffin over the area ff, for example, will also impart nonadhesive properties. I may prefer to leave a minute uncut portion in the line b-b in the center of its arc, in order to facilitate sealing the carton 'on theordinary sealing machines.

I have shown both side closing flaps 4- -4,

having withdrawal tabs 8 formed with cut lines gg outlining the front and sides of the tabs, and with lines hh along the line of attachment to the flaps 4+4. WVhen the side walls are folded over, the lines hh should lie substantially in alignment with the line dd. It should be noted that the cut lines which outline the sides of the withdrawal tabs taper out somewhat from the line of attachment toward the open end. The reason for extending the lines of out which outline the sides of the Withdrawal tabs in such directions is so that when the dispensing spout is withdrawn through the withdrawal tab openings the score lines ee which form the lines of attachment of the dispensing spout side walls to the base of the spout will be gradually folded back without liability of bending improperly or tearing off.

It will be observed that the size of the withdrawal tab in the side closure flap f to the left in Figure 1 is slightly smaller than the withdrawal tab in the flap 4 which isshown at the right. It is preferable to have the withdrawal tab on whichever flap 4 is closed in first on the end flap 5, of relativelysmaller proportions. The principle, to be observed in this connection is that no perfect folding of the flaps will ever occur, so when an inner part is required to pull out through an opening in an outer one, by making the outer one slightly larger than the inner'one, there will be no likelihood of improper or imperfect registry.

In the drawings, the flap shown to the left in Figure 1 is supposed to fold over first on the end flaps. The tapering of the cut lines outlining. the sides of the withdrawal tab is onlynecessary on that'flap which is to lie against the-end flap. In Figure 1 the closing flap to the left is the one of the flaps in which the tapering of the lines outlining the side of the withdrawal'tabs enforces easy bending of the score lines which form the line of articulation of the side walls and the base of the dispensing spout. The tapering of the side walls of the withdrawal tab on that one of the side closure flaps. which is to be folded over andsealed last is merely for purposes of'clearance and to prevent regis which might cause leakage.

The sealing of the top closing flaps of the carton is preferably performed on a bottom sealer. One well known type of bottom sealer has a roller which first folds down and applies a layer'of glue to the end closure flaps.

Then the machine has another roller which moves sideways across the carton and folds down one of the side flaps, to which glue is also applied. The other side closure flap is then folded over and pressure isapplied to the outer surface of the last flap, and, since the carton is normally carried on a block which fits the shape, of the inside of the carton, agood tight sealed joint can be made.

' The treatment of the upper surface of the try of cut lines dispensing spout to make the board non-adhesive to glue prevents the wings of the dispensing spout from adhering to the under surface of the first one of the side closure flaps which is to be folded over on it.

While I have shown my dispensing spout and withdrawal tab arrangement with the dispensing spout on the'underneath one of three overlapping portions of the carton, it is within the scope of my invention to vary the position of the dispensing spout with relation to the Withdrawal tabs. The dispensing spout might be formed in one of the side I claim as new and desire to secure by Letters I Patent, is

1. A" carton having at least three overlapping portions, and having a base and side Walls of a dispensing" spout outlined in cut lines in an underlying portion, with withdrawal tab portions outlined in overlying overlapping portions.

2. A carton having at least three overlapping portions, and having a base and side walls of a dispensing spout outlined in cut lines in an underlying portion, with withdraw-al tab portions outlined in cut lines in overlapping portions.

3. A carton having at least three overlapping portions', and having a base and side walls of a dispensing spout outlined in cut lines in an underlying portion, with withdrawal tabportions outlined in cut lines in overlapping portions, said dispensingspout having a base articulated to an underlying portion, and said withdrawal tabs having lines of articulation formed to register with the line of articulation of the base of the dis pensing spout and the underlying portion to which it is attached.

4. A carton having overlapping portions in which an underlying portion has a dispens-' ing spout outlined in readily frangible lines, said dispensing spout having a base with sides articulated thereto, and a portion overlying said portion having a withdrawal tab formed in readily frangible lines, the outline of the withdrawal tab being slightly larger than the base of the spout, and the surface of an ,engaging face of at least one of said overlapped portions. treated so as to be impervious to glue adhesion, whereby the sides of the spout will not adhere to an overlapped portion during the sealing of the overlapping portions,"

- said portion having a withdrawal tab formed in readily frangible lines, the outline of the withdrawal tab being slightly larger than the base of the'spout, and the surface of an engaging face of at least one of said overlapped portions treated so as to be impervious to glue adhesion, whereby the sides of the spout will not adhere to an overlapped portion during the sealing of the overlapping portions, one on another, and the outline of the withdrawal tab being tapered from base to front to facilitate the bending of the sides of the base of the dispensing spout during withdrawal of the spout. 6. A carton having at leastthree overlapping portions forming an end closure with a dispensing spout outlined in readily frangible lines in an underlying portion, said dispensing spout having a base and articulated winglike sides, withdrawal tabs formed in overlapping portions, said tabs being of such size as to admit the withdrawal therethrough of said spout base with the wings thereof folded at right angles to said base, said withdrawal tabs being successively of larger size than said s out base, whereby the spout base may ready pass through the innermost of the openings formed by the withdrawal tab in the undermost of those overlapping portions having tabs therein, and whereby the undermost withdrawal tab will readily pass through the opening in the overlapping portion in which the outermost withdrawal tab is formed.

7. A carton having at least three overlapping portions forming an end' closure with a dispensing spout outlined in readily frangible lines in an underlying portion, said dispensing spout having a base and articulated wing-like sides, withdrawal tabs formed in overlapping portions, said tabs being of such size as to admit the withdrawal therethrough of said spout base with the wings thereof folded at right angles to said base, said withdrawal tabs being successively of larger size than said spout base, whereby the spout base may readily pass through the innermost ofthe openings formed by the withdrawal tab in the undermost of those overlapping portions having tabs therein, and whereby the under-most withdrawal tab willreadily pass through the opening in the overlapping portion in which the outermost withdrawal tab is formed, and the upper surface of the first mentioned underlying portion treated so as to have areas thereof in which the wing-like sides of the spout are formed, which will be impervious to glue adhesion so that the closure flaps may be sealed with a uniform layer of glue applied 7 to the overlappingportions during the sealing operation.
